SPECIFICATION forming part of Letters Patent No. 437,230, dated September 30, 1890.

Application filed April 30, 1890.

To all whom it may concern.-

-Be it known that I, HENRY L. NoRoRoss, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Elevated Railroads, of which the following, taken in connection with the accompanying drawings, is a specification. 1

The object of my invention is to produce an elevated railroad that will be light and cheap in construction, and will not interfere with street travel, and obscure very little if any light.

The invention consists in various details of construction, as hereinafter fully described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of an elevated railroad and car embodying my invention. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a plan of the road, drawn to a smaller scale. Fig. 4: shows a transverse vertical section of two roadways arranged one above the other. Fig. 5 is adetail view showing the method of securing the rails to the longitudinal girders. Fig. 6 is a View of the rollers that are arranged in front of the car-wheels. Fig. 7 shows, respectively, a side view and a front view of the rollers that are secured to the side of the car.

A A represent columns or posts arranged in a single row on each side of the roadway, each pair supporting a box-girder B.

O O are I-girders that extend from one boxgirder B to the one next adjacent. These I- girders are arranged in pairs at a suitable distance apart, each pair supporting a plank D, to which the rails E are secured by spikes 6 (see Fig. 5) in the usual manner.

The planksD are secured at suitable intervals by means of bolts F, that pass between the III-girders and are secured underneath by nuts f, a plate F being interposed between the girders and nuts.

G G are. channel-irons, supported by standards H, that are braced by bars J. Each pair of channel-irons is of a width apart to just allow acar to pass between them. The inner ones are continuous, but in the outer ones a space is left at each station R for the passengers to pass to or from the car. The stations R are reached from the sidewalk by a flight of steps L.

Serial No. 350,018. (No model.)

M represents a car, to the under side of which at each end is secured a frame N, in which are mounted two rollers P, that stand a short distance above the rails E, so that should a wheel of the car break or the car be derailed the rollers will come into contact with the rails and support the car. To the sides of the car are secured two or more frames Q, each carryinga vertical roller S and a horizontal roller S. These frames are arranged are a few inches away from the channel-irons G, and are intended as a safeguard in case the rollers P are not sufficient or should become disarranged by any accident.

In Fig. i I have shown two double tracks arranged one above the other. It will be seen that by this construction the sidewalks are left clear, only a narrow space being required where the stations are arranged, the roadway is not obstructed, and very little if any light will be obscured, and the cars can be run by steam-power or electricity, as may be desired.

What I claim is 1. An elevated railroad consisting of boxgirders B, extending transversely across the roadway, and supported by posts or columns A, longitudinal I-girders arranged in pairs between the box-girders, the planks D, secured to the I-girders, and the rails E, substantially as set forth.

2. In combination with an elevated railroad having a roadway supported by two rows of posts or columns and having rails E E upon which the cars run, channel-irons G, arranged on each side of said rails and supported above the track by standards at or about a height equal to half the height of the car, substan tially as and for the purpose set forth.

3. In an elevated railroad, rollers S S, mounted at right angles to each other in a frame Q, secured to the side of the car, in combination with longitudinal channel-irons G, supported so as to be nearly in contact with said rollers, substantially as and for the purposes set forth.

Intestimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.
